Issue/Bug Description: I have an Oontz angle 3 bluetooth speaker that has worked well for a couple years now. After upgrading to 21.10, its sound quality gets choppy and distorted when it automatically pairs to my machine. If I go into bluetooth settings, remove the speaker, then set it up again, it works fine once more. It only happens when I let it auto-pair, and it doesn't happen on 21.04.

This was tested on multiple machines, but it seems to only happen with this bluetooth speaker. Both the PowerBeats T3 bluetooth speaker in the lab and my Anker Soundcore Q20 headset work fine if they auto-pair to a device.

Steps to reproduce (if you know):

• Turn on bluetooth speaker and connect to it in the Bluetooth section of Gnome Control center
• Test sound, but it should sound fine
• Turn off bluetooth speaker
• Turn bluetooth speaker back on and let it automatically pair with the machine. Sound output may not automatically be set to the bluetooth speaker, so select it in sound settings if necessary.
• Test sound through bluetooth speaker. It will sound choppy, as if it's set to the wrong sampling rate.

Expected behavior: Bluetooth speaker should sound normal after automatically pairing.

Other Notes: Workaround: remove the device in bluetooth settings and manually set it up again. This will make it work until the bluetooth speaker is turned off again.
